Report of Independent Registered Public Accounting Firm

To the Management of Santander Consumer USA Inc. and Santander Bank, N.A.

We have examined management’s assertion, included in the accompanying Management’s Assessment of Compliance with SEC Regulation AB Servicing Criteria, that Santander Consumer USA Inc. and Santander Bank, N.A. (the “Asserting Parties”) complied with the servicing criteria set forth in Item 1122(d) of the Securities and Exchange Commission’s Regulation AB for all publicly registered transactions backed by auto loans for which the Asserting Parties acted as the servicer or subservicer (the “Platform”), as of December 31, 2025 and for the year then ended, excluding criteria 1122(d)(1)(iv), 1122(d)(2)(iii), 1122(d)(2)(vi), 1122(d)(4)(ix), 1122(d)(4)(x), 1122(d)(4)(xi), 1122(d)(4)(xii), and 1122(d)(4)(xiii), which the Asserting Parties have determined are not applicable to the servicing activities performed by it with respect to the Platform. As described in management’s assertion, for servicing criteria 1122(d)(2)(i), 1122(d)(4)(i), 1122(d)(4)(ii), 1122(d)(4)(iv), 1122(d)(4)(vi), 1122(d)(4)(vii) and 1122(d)(4)(viii), the Asserting Parties have engaged various vendors to perform the activities required by these servicing criteria. The Asserting Parties have determined that these vendors are not considered “servicers” as defined in Item 1101(j) of Regulation AB, and the Asserting Parties have elected to take responsibility for assessing compliance with the servicing criteria applicable to each vendor as permitted by Compliance and Disclosure Interpretation 200.06 of the SEC Division of Corporation Finance’s interpretations of the rules adopted under Regulation AB and the Securities Act and the Exchange Act (“Interpretation 200.06”). As permitted by Interpretation 200.06, the Asserting Parties have asserted that it has policies and procedures in place designed to provide reasonable assurance that the vendors’ activities comply in all material respects with the servicing criteria applicable to each vendor. The Asserting Parties are solely responsible for determining that they meet the SEC requirements to apply Interpretation 200.06 for the vendors and related criteria as described in its assertion, and we performed no procedures with respect to the Asserting Parties’ determination of its eligibility to use Interpretation 200.06. Appendix A to management’s assertion identifies the individual asset-backed transactions and securities defined by management as constituting the Platform. The Asserting Parties’ management is responsible for its assertion and for the Asserting Parties’ compliance with the applicable servicing criteria. Our responsibility is to express an opinion on management’s assertion about the Asserting Parties’ compliance with the applicable servicing criteria based on our examination.

Our examination was conducted in accordance with the attestation standards of the Public Company Accounting Oversight Board (United States) and in accordance with attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management’s assertion about compliance with the applicable servicing criteria is fairly stated, in all material respects, and, accordingly, included examining, on a test basis, evidence about the Asserting Parties’ compliance with the applicable servicing criteria and performing such other procedures as we considered necessary in the circumstances. Our examination included testing of selected asset-backed transactions and securities that comprise the Platform, testing of selected servicing activities related to the Platform, and determining whether the Asserting Parties processed those selected transactions and performed those selected activities in compliance with the applicable servicing criteria. Our procedures were limited to the selected transactions and servicing activities performed by the Asserting Parties during the period covered by this report. Our procedures were not designed to detect noncompliance arising from errors that may have occurred prior to or subsequent to our tests that may have affected the balances or amounts calculated or reported by the Asserting Parties during the period covered by this report. We believe that our examination provides, and that the evidence we obtained is sufficient and appropriate to provide, a reasonable basis for our opinion. Our examination does not provide a legal determination on the Asserting Parties’ compliance with the servicing criteria.
